In geometry, a translation is the shifting of a figure from one place to another without rotating, reflecting or changing its size. This is done by moving the vertices of the figure the prescribed number of spaces on a coordinate plane and then drawing the new figure.
These PFDs are designed to keep the wearer in a vertical position, but it is the wearersâ responsibility to maneuver themselves into a face-up position. Type III PFDs will keep unconscious wearers face-up just as well as a Type II vest.
For an unconscious patient, the best position is side-lying with the patients head turned toward you in either a semi-Fowlers position or with the head of the bed flat. Placing the patient in one of these positions allows fluid and any oral secretions to collect in the dependent side of the mouth and drain out.
